US persons: a minimum loan of £1,000,000 on a prime London or southern property

Butterfield lends to high net worth clients at home and overseas and sets no citizenship test, so the gate is ticket size and postcode. Its current guidelines, dated February 2024, price every facility at a margin over Bank of England base rate with a 2.5% minimum pay rate, and publish no rates, so the figure is quoted to you. Nothing it publishes mentions US citizens.
